渤海湾全新世海侵是第四纪晚期全球气候变化的重要事件,以往研究表明渤海湾西岸全新世海侵已经深入到文安县。本次研究在文安县西北30km的雄县15BZ02剖面第8层底部灰褐色粉砂中发现大量缢蛏新种,壳体呈斜交或垂直层面产出,反映了潮间带...渤海湾全新世海侵是第四纪晚期全球气候变化的重要事件,以往研究表明渤海湾西岸全新世海侵已经深入到文安县。本次研究在文安县西北30km的雄县15BZ02剖面第8层底部灰褐色粉砂中发现大量缢蛏新种,壳体呈斜交或垂直层面产出,反映了潮间带中下部的内湾、河口环境。同时,在该层段发现了海相介形虫Tanella opima。由此推断,渤海湾西岸海侵于全新世中期(6970~6670cal a BP)达到最大范围,海水曾经到达雄县北。展开更多
